Vibration switch

  1. Nov 17, 2004 #1
    Say a vibration switch is used as a trigger in a bike alarm. I know it will be more sensitive than a tilt switch, but once the vibration switch has been triggered, does it return to its "normally open" status simultaneously?

    It’s probably safe to assume that there is an “off the shelf” device to suit your needs. If not, the switch can be used to activate a relay. Relays have normally “open” contacts and normally “closed “ contacts. Once a relay is activated the status of the switch can be ignored. In other words, using one or more relays, a simple logic circuit can be used to achieve your needs. If you have some knowledge of electronics, solid state components can be used in place of the relays.

    One thing that can be used as a vibration sensor is a microphone.
    Turning it into a switch is the design challenge.

    Other than that it's time to do a product search and read specs.
